"We have been left wailing" over Britain's Channel 4 video that shows a group of soldiers surrounding a half-naked Tamil lady," DMK chief M Karunanidhi said.
The video claims that the woman, a Tamil TV presenter who had served in the LTTE, was executed after being captured by the troops and not during the final battle as claimed by the government. She was found dead with her clothes stripped.
Political parties and various outfits are strongly opposed to India's participation in the Commonwealth Heads of Government Meeting in Sri Lanka this month, with the Tamil Nadu Assembly recently adopting a resolution demanding New Delhi completely boycott it and also temporarily suspend that country from Commonwealth federation till Colombo ensured equal status for Tamils.
Karunanidhi said Tamils all over the world expected India to boycott CHOGM as a mark of rapping Sri Lanka for the latest video and grab the attention of the international community towards the incident.
Sri Lanka had dismissed the video documentary as "fake", saying attempts were being made to discredit the army ahead of the Commonwealth conference.
"It is nothing new for Channel 4 to discredit Sri Lanka at important times such as the UN Human Rights Council sessions and the upcoming Commonwealth conference," military spokesman Brigadier Ruwan Wanigasuriya had said.
